Special Assessment District #228

Removing boulders to allow trenching for utilities

Removing boulders to allow trenching for utilities

Owner: City of Albuquerque
Engineer: Wilson & Company
Location of Project: Albuquerque, NM
Contract Amount: $26,750,711
Completion Date: June 2014

AUI’s largest site development project to date, Special Assessment District (SAD) #228 consisted of 72-acres of site work including:

  • Over 65,000 CY of rock excavation requiring extensive blasting and rock trenching
  • Over 200,000 CY of import fill material
  • Over 50,000 TN of base course material
  • Over 200,000 SY of superpave asphalt concrete
  • Over 90,000 LF of concrete work that included curb and gutter, sidewalks, ADA ramps, and driveways
  • Over 12,000 LF of reinforced concrete pipe in various diameters from 18-in to 96-in
  • Approximately 38,000 LF of 8-in to 18-in diameter PVC sanitary sewer pipe installation, 2,000 LF of 6-in ductile iron forcemain, and 1,500 LF of 2-in PVC forcemain, plus a lift station
  • Over 200 manholes ranging in diameter from 4-ft to 10-ft
  • Approximately 42,000 LF of 4-in to 12-in diameter PVC waterline requiring over 30,000 lbs of ductile iron fittings
  • Water and sanitary services to approximately 430 individually owned properties
  • Over 66,000 LF of dry utility installation to include electrical, communication, and natural gas infrastructure
  • Signalization and lighting
  • Signage and striping
  • Garden walls and landscaping
  • Bike trail

The extensive rock removal on the project had numerous challenges. Basalt formations were very diverse and unpredictable; a single formation could contain voids, veins, and cracks which made blasting difficult due to the unpredictable release of pressure. Blasting was required directly above existing residences and both above and adjacent to active arterial roadways. The entire site was adjacent the Petroglyph National Monument, containing federally protected artifacts. We mitigated these challenges by using vibration and air blast monitoring for all rock blasts, utilizing both permanent and roving monitoring stations.

The fixed Owner’s budget with minimal contingency required careful budget management, especially since the entire design was preliminary and had to be constantly modified to meet the intent. We were also required to provide access to over 300 private land owners throughout the project.

TA-1 Waterline Rehabilitation

Sandia National Labs (SNL)
Contract Amount: $1,284,673.10

Improvements to the water distribution system in Technical Area 1 on Sandia National Laboratories (SNL) utilizing trenchless technology to replace deteriorated portions of the waterline throughout the tech area. A total of 4,450 LF of 6” to 12” waterline was replaced during this project; approximately 66% through pipe bursting and 34% through open-cut-and-replace.

There were approximately 700 potholes through the duration of this project. At one intersection alone, there were 21 undocumented utilities. Upon locating these utilities, AUI would coordinate with SNL representatives to get a GPS reading on the utility line, determine if the line was active or inactive, and add the line to the as-built documents for this project. Each situation concerning an unknown underground facility presented unique challenges including the need for penetration permits, and modification to the proposed waterline installation plan to avoid conflicts with these facilities.

This project occurred throughout Technical Area 1 on various streets heavily traveled by both vehicles and pedestrians, near SNL employee work areas and parking lots. The AUI team was challenged with keeping traffic flowing, keeping the affected work areas and employees informed, maintaining safety and space for pedestrians, and promoting construction area safety awareness for those who might find themselves in the construction area.

Throughout this project, maintaining water service to offices and laboratories was a critical issue. AUI was able to work out a schedule with the SNL representatives so that the shoo-fly or bypass waterlines could be set in place and water service to these facilities would only be interrupted long enough to connect into these temporary lines (less than 2 hours). The process would be reversed to re-connect the facilities to the water distribution system once the waterline serving the facility was replaced.

AUI is proud to have participated in this project for SNL that was an adventure into utilizing trenchless technology as an efficient and effective means of rehabilitating waterline in a highly congested area for which maintaining the water supply was a crucial issue.
